My iMac locks up whenever I open Safari
I cannot use Safari at the moment, since it always locks up. All other functions (mail, messages, apps) are working fine, but Safari causes it to lock up.

Have you restarted your Mac lately?
Rebooting is the best first step in troubleshooting.
If a simple reboot of your Mac doesn’t fix things, see if the problem still happens in safe mode.
How to use safe mode on your Mac - Apple Support
Safe mode will often correct weird software behavior by forcing the OS to clear caches, do disk repair and other self-maintenance and housekeeping and temporarily disables third-party mods.
Does the same thing happen while in Safe mode?
You can exit safe mode by restarting your Mac normally, then reevaluate the problem.
